Tool for building an extensive click dummy [on hold]

For testing of a new design and restructure of a sub-section on our website we work on a click dummy (hifi prototype with linked screens). We build it in order to run a few user tests before deciding on the IA. We are currently using Sketch - but the linking and duplicating of screens turns out very effortful.

Does anyone know a better tool that can simplify the process?

Thanks!
